I'd like to know the number of eCommerce Web sites that are currently
in the United States (or the world if unable to give U.S. stats). I've
noticed that this question has been asked before and no one was able
to give an answer. However, that was a year ago and I'm hoping someone
can now meet the challenge. I'm not sure if this would help, but
nearly all eCommerce sites accept MasterCard/Visa. If there's
aggregate data by either credit card processors or MasterCard/Visa on
the number of eCommerce clients they have, that would be the magic
number (or at least approximate). Thank you in advance.
